Pop singer BRITNEY SPEARS surrenders herself to alter-ego BRITANNIA while
performing - because her other persona is far wilder than she is.

The ME AGAINST THE MUSIC beauty insists she is so shy in real life, she
has to transform into brash Britannia to keep her fans entertained.

Britney explains, "This alter ego takes over when I am on stage. She is
really wild and daring and a much more impulsive performer than I am. Her name
is Britannia. When I am her I feel I can take on the world, normally I am
pretty shy."

Britney is not the first pop babe to reveal a split personality - Beyonce
KNOWLES' alter ego is Sasha and Christina Aguilera transforms into raunchy
XTINA when on stage.
